The manlands always felt out of place in the cube : coming to the battlefield tapped was too much of a loss of tempo, and with 3 painlands and 4 fetches, there is already enough fixing for 2 players.

On the other hand, the desert cycle from Hour of Devastation seems like it was meant to be in this cube. Each of the 3 deserts provides a nice effect in line with its color game plan and costs life to be used. They make for a nice redundancy with the Odyssey lands as "Spell lands". Since the mana curves tend to be pretty low, it's always nice to have a side effect on some of the lands.
